I assign readings from this book and my students not only actually do them (!) but also tell me that the readings really help them. Awesome text!

Testing for Underpowered Literatures How many experimental studies would have come to different conclusions had they been run on larger samples? I show how to estimate the expected number of statistically significant results that a set o...

Under the counterfactual being studied we would also double the number of treatment clusters! So it really appears that lots of RCTs are either overpowered or are chasing something close to a true null. Exactly 80% powered studies seem quite rare. Here is the paper if you are interested:

My JMP was on exactly this subject! I estimated that doubling the sample size of every econ rct would only increase power by 7 pp on average. It turns out that in econ the true power of most RCTs (conditional on the true effect) is either very high (little benefit to doubling) or very low.

Can we tell from the data when and how treatment effects generalize across different individuals and contexts? Exciting new working paper, joint with Emily Breza and Arun G. Chandrasekhar that studies generalizability for applications to external validity, effect heterogeneity and model discovery
